Just pickup the npr 1month ago so I'm not sure on mpg. But what i researched from other guys on this site was it was somewhere in the range of 14mpg loaded with trailer for the turbo diesel. For the measurements I can tell you that today I cut an interior shelf for the front of trailer at 78" wide add the 3/4 plywood sides I'm at 79.5". I would guess the back would be a little wider. I think it's the black that makes it look a little smaller than it really is. I have maybe 1 ft or so walking space on trimmer side and few inches on the blower side. Plus there is decal on the rear that says 7x16...

Its not a true 7 footer, because if it was it would be 84" wide meaning you would have a foot of space on each side of the mower deck witch is 60". I've seen it before its nothing that uncommon that the trailer is 79" wide but there still calling it 7x16.

You will find the guards tend to come off with most companies because it's just extra weight and it really doesn't keep you from getting beaned by debris. You must watch your guys string length once the guards come off because longer lines put more stress on the clutch and engine. The engine will not operate at the intended rpm if the line gets much longer then the OEM length. Longer line equals more heat.

Plantscape that is a nice setup you have. You ain't lying about thought and $$$. Love the wrap that looks amazing. I'm working on lettering mine but I really want to redesign to whole thing. Here is a thread of want my vinyl man has sent me so far. He doesn't do design its just the picture I had from my previous trailer magnets on my truck. Do you have any pictures of the ceiling selves?
